Abstract
The tribal and subtribal structure of the braconid subfamily Opiinae is dismantled, and several changes in the generic classification are made. Thoracoplites Fischer and Aspilodemon Fischer are removed from the Opiinae. Utetes Foerster and Pseudorhinoplus Fischer are elevated to generic rank and Bracanastrepha Brèthes is treated as a subgenus of Utetes. Five generic names currently in use are treated as synonyms of Opius Wesmael, Rhinoplus Foerster is synonymized with Biosteres Foerster, and Kephalosema Fischer is synonymized with Hydrangeocola Brèthes. Relationships of species groups formerly included in the subtribe Biosterina are discussed in phylogenetic terms.
